This beautiful silk screen litho is signed and numbered 209 of 250. Frame is original to period. Psychedelic patterns that emerge from early computational experiments parallel Optical Art imagery of the sixties. Op Artist Victor Vasarely used the “Alphabet Plastique” to create optical illusions. Each color and shape was assigned a variable that could easily be manipulated. The kinetic relationship of color and shape gave dimensionality to his work. He and many other Op Artists created paradoxical imagery that challenged spatial limitations.
